ROTARY BRUSH.

Specification of Letters Patent.

Patented Dec. 312, 1916.

Application filed. November 28, 1914. Serial No. 874,416.

7 provide a rotary brush which will have continually passing therethrough a stream of water so that any particles of grit or dirt worked off of the vehicle willbe washed out of the brush and will-not be worked along with the brush and thus injure the finish upon the vehicle.

Another object of the invention is to provide a brush having a suflicient discharge area to permit the escape of water from the motor which rotates the brush so that the motor will not be interfered with.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the, 'same portion throughout, but I am aware that there are many modifications thereof.

Figure 1 is a side elevation of the complete apparatus, only a few of the bristles being illustrated, Fig. 2 is a longitudinal sectional view through the enlarged end of the apparatus, and Fig. 3 is a side elevation of the turbine wheel used to drive the brush.

The numeral, 1 represents a pipe of such length as may be desired, usually two or three feet long to which pipe an enlarged head 2 is connected by means of the pipe fitting 3. The other end of the pipel is provided with anenlarged portion a into which a hose is adapted to be screwed and a cut-ofi yalve having a handle 5 is installed in the portion 4. The head 2 is internally threaded at 6 to receive the motor frame 7, said frame having a boss 8 forming a bearing for the shaft 10 upon which} the motor is-mounted, said motor having vanes 12 against which water from the nozzles 9 strikes. It will be understood that there is such a number of the nozzles 9 as is deemed necessary to supply the Water to drive the-.motor and wash the vehicle.

The. head 23 extends transversely across the end of the motor holding frame and affords 'a bearing for a short shaft 17, which shaft has gears 13 and 18 thereon. The head 23 is secured in placeby a suitable number of screws 24; and it is'also provided with a thrust block 15 held in place by means of the screws 16 for the end of the shaft 10 to bear against.

The shaft 10 carries a gear i l in mesh with the gear 13 and the shaft 20 having a bearing at one end in the head 23 and at the other end at 21 in a block held by means of the arms 22 connected. with the head 23 and carries a gear 19 in mesh with the gear 18. A collar 20 bears on the block 21 and prevents the shaft 20 from moving long'itudinally. The end of the shaft 20' is threaded at 25 to receive the hub 24: on one of the brush members 27 and the brush holding member 27 is connected with the hub by means of a spiral rib 26 which rib tends to assist in throwing the water out toward the end'of the brush.

The brush member is made of two parts and the two parts are held together by means of the screw 29 which passes through the part 28 into the hub 24 and into a notch in the side of the shaft- 20 thereby preventing the brush headfrom coming ed the shaft and also afi'ording means whereby the brush head is rotated.

In order to confine the water as much as possible a sheet metal hood 34 is placed on the motor holding frame and its open end extends into the brush holding member a short distance, while the brush head is provided with a plurality. of large openings 30 to admit of a free discharge of the water i from the center of the brush.

runs at a very high speed, but it will be observed that by a double gear reduction that the brush-rotates very slowly, thus the user is able to efiectively clean the surfaces desiredv i 4 ing an enlarged head witha transverse par- 'tition, said partition having a plurality of openings therethrough, a water motor in contact with said partition and having vanes which travel over the openings therethrough, a frame carried by the head and having a hearing at its outer end, a brush shaft in alinementwith the motor axis extending through said bearing and into a fixed bearing in the hollow head, a series of reduction gears between the motor and the shaft last mentioned whereby it will be driven at a slower rate of speed than the motor shaft, a hollow perforated brush carried by'the shaft, said brush extending over the lorii'sh iframe to which the shaft bearing is connected, and a funnel to direct the escapin waterinto the hollow brush.

2. in a rotary brush, a hollow handle having an enlarged head at one end thereof,

moat is a cylinder screwed into said enlarged head and having apartition' and a bearing connected therewith, a Shaft extending through said bearing and carrying a motor wheel with its vanes'in' contact with the openings through the partition in the cylinder, a frame connected with said cylinder, said frame having a bearing for a reduction gear shaft and bearings for the brush shaft in alinement with the motor shaft bearing, a brush shaft in .alinement with the motor shaft having a hollow perforated brush on its outer end, means to direct the water being discharged into the hollow brush, and suitable gears for driving the brush from the motor at a slower rate of speed than the motor.

In testimony whereof I have hereunto set my hand this 18th day of November, A. D. 1914:, in the presence of the two subscribed witnesses.
